`4`Iihis invention relates in general to iin-` proveinentsin snow plows for removing snow` from streets, roads or highways, and in which apparatus there is provided an impeller or rotor for receiving and delivering thevsnow.

from the vmachine anda scoop like device fer gathering and Vdirecting the snow to` theimpeller, the scoopy and` impeller being pref'- erably arranged in an inclined position at the forward endof the machine, and one of the objects of theinvention to provide iinproved means in connection with a scoop for assisting in conveying the snow to the, impeller and for breaking up and disintegrating the snow as it is delivered to the impeller- A further object is to provide in connection with the iinpeller improved means for feeding and delivering the snow .to the iinpeller.

A further object is to provide an improved apparatus of this character which will be of a simple, durable and compact.construction number of these shafts may vbe provided and and effective and efficient in operation.V Y y To the attainment ofthese ends and the ac@ coinplishinent of other new and useful objects as will appear, the invention consists iii the features of noveltyin substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown inthe accompanying drawing illustrating this invention, and in which j Figure 1 is a vertical sectional view as taken on line 1-1, Figure 2.

Figure 2 is a top plan view of the scoop and v feeding mechanism.

Referring more particularly to the drawing the numeral 10 designates generally a scoop like device, the lower end of which preferably projects beyoiida casing 1l, and

the scoop is of a width considerably greater than the diameter of an opening l2 in the bottom of the scoop and which opening has communication with the casing 11, forming the inlet thereto. Leading from the casing 11 is a discharge spout 13 through which the `material which enters the casing is delivered.

Arranged within the casing 11 is a rotor designated generally by the reference numeral 14, of any suitable construction, and this rotor is connectedwith a shaft 15 journaled in suitable bearings. The shaft has connected with it and on the outside of the casing a gear wheel 16 which meshes with a gear wheel 17 and which latter is connected with a shaft 18 for rotation therewith, the shaft 18 receiving'its motion from any` suitable source (not shown). j i

Arranged within the scoop like device 10 is a deflector 19 which ,is arranged in the rear of the opening 12 and is shaped to partially encompass 4the opening. This Mdeflector preferably inclined to the bottoni of the scoop and preferably extendsentirely thereacross, and serves to assist in directing the snow into the opening 12. n i A hood like `closure 2O may be provided for a portion of the scoopand is preferably pivotally mounted as at 21 and serves as a means for preventing the snow from traveling out of. the top of the scoop, andis pivotally niount-` ed so that the snow will automatically control the' rising'thereof. Ai'franged withinthe scoop, preferably adjacent the bottoni thereof and f extending longitudinally of the scoop are a .plurality of shafts 22nioiinted in suitable bearings., Any

are connect-ed so as to bev driven from a single source of power preferably through the iiie-V wheel connected with a shaft 25, the latter f beingjournaled in suitable bearings QG. The shaft 25 may receive its motion from any suitable source such as from the shaft ifi through the medium of a beveled gear o" connected with the shaft 25, and which gear f meshes with the gear 17.

Connected with the shafts 22 for rotation therewith are spiral bladesor-conveyors 2S, one end of which preferably terminates adjacent tlie forward end of the scoop and the other end terminates adjacent the opening 1Q. Connected also with the shafts 22 for rotation therewith are a series of elements 9.9 which operate upon the snow for breaking up` or disintegrating it, and any number of these. elements 29 may be provided.`

A conveyor 30 preferably in the form of a spiral, is connected .with the shaft 15 of the rotor 14 and projects into the scoopV 10 with its axis co-inciding with the axis of the rotor. This conveyor 30 may be of any desired diameter and length but is of a length to terminatewithin the scoop. As the rotor is operated the conveyor 30 also operates and forces Ait) or feeds the snow which is within the scoop into or through thel opening 19 in'the bottoni of the scoop to the rotor where itis caught and delivered through the discharge outlet 13. j

lVith this improved construction it will be manifest that there will be a eoi'itinuousr feed ing ol the snow by the conveyors 28 and 30` and the elenients 29 will operate upon the snow and any ice which may be present, as well other foreigirarticles, totdisintegrate or break up the same before being delivered to the rotor.

ll'hile the preferred torni ot' the invention has been herein shown and described'it is to be understood that variousl changes may be made in the details ot construction and in the combination and arrange'i'nentofthe several parts. witliintlie scope ot the claims, without departing lroin the spirit ot thisinvention, and it desired any other suitable mechanism may` be proridml'lir rotating the shafts on which the conveyors 528 and ele,` ments 29 are mounted.

That is claimed as new istl. A, snow plow includingI a easing having an inlet. and a discharge outlet. a rotor in the casing. a .scoop like device discharging into the easing.y a, shaft adjaient and extending lengthwise otthe bottomot thesc'oop and lengthwise of the `direction ol' travel ot' the scoop, means lor rotating the shaft', andra conveyor blade mounted upon theshatt and operating to leed the material through the scoop and along the bottom thereof tothe inlet ol the rotor casing.

2. it Asnow plow including a casing haring an inlet and a discharge outlet, a rotor in the casing, a scoop like structure, discharging into `the casing, a shalt adjacent and extending lengthwise ot the bottom oit the scoop and of' the direction ot travelolthe scoop, a coin veyor mounted upon the shaft' for 'conveying the. material along the bottom oi the scoop to the rotor easing, means also connected with the shaft and operating within thelscoop to disintegrate the material, and means' `l'or rotatiiig the shaft.
